types of infinite 1D helical chain structures, both of which contain 24-membered metallocyclic rings. Complex 3 is composed of 1D zigzag chains, which further form a 3D supramolecular architecture by weak C–H···S and S···I interactions. Complex 4 also features a 3D supramolecular network assembled from 2D rhombus-shaped layer through intermolecular hydrogen bonding. These structures indicate that the
由 1, 3-bis(pyridine-3-carbonyl)imidazolidin-2-thioxo (3-bpit) 和 1, 3-bis(pyridine-4-carbonyl)imidazolidin-2- 构成的一系列镉 (II) 配位聚合物硫代(4-bpit),即[Cd(SCN)2(3-bpit)2]·2(CH3OH)}n(1),[Cd(NO3)2(3-bpit)2]·2 (CH3OH)}n(2)、[CdI2(4-bpit)]n (3) 和 [CdCl2(4-bpit)4]n (4) 被制备并通过单晶 X 射线衍射表征。配合物 1 和 2 显示出不同类型的无限一维螺旋链结构,两者都包含 24 元金属环。复合物 3 由 1D 之字形链组成,通过弱 C–H…S 和 S…I 相互作用进一步形成 3D 超分子结构。复合物 4 还具有由 2D 菱形层通过分子间氢键组装而成的 3D
